Surgical treatment of endometriosis

Surgical treatment of endometriosis

Surgical treatment for endometriosis can be useful when the symptoms of endometriosis are severe or when there has been an inadequate response to medical treatment. Surgery is the preferred treatment when there is anatomic distortion of the pelvic organs or obstruction of the bowel or urinary tract. Surgical therapies for endometriosis may be either classified as conservative, in which the uterus and ovarian tissue is preserved, or definitive, which involves hysterectomy (removal of the uterus), with or without removal of the ovaries.
Conservative surgery is typically carried out by laparoscopy. Endometrial implants may be excised or obliterated by laser. If the disease is extensive and anatomy is distorted, laparotomy (opening of the abdominal wall via a larger incision) may be required.
While surgical treatments can be very effective in the reduction of pain, the recurrence rate of endometriosis following surgical treatment has been estimated to be as high as 40%. Many doctors recommend for women who have had surgery for endometriosis to take oral medications after surgery to help maintain symptom relief.

What causes endometriosis?

What causes endometriosis?

The cause of endometriosis is unknown. One theory is that the endometrial tissue is deposited in unusual locations by the backing up of menstrual flow into the Fallopian tubes and the pelvic and abdominal cavity during menstruation (termed retrograde menstruation). The cause of retrograde menstruation is not clearly understood. But retrograde menstruation cannot be the sole cause of endometriosis. Many women have retrograde menstruation in varying degrees, yet not all of them develop endometriosis.
Another possibility is that areas lining the pelvic organs possess primitive cells that are able to grow into other forms of tissue, such as endometrial cells. (This process is termed coelomic metaplasia.)
It is also likely that direct transfer of endometrial tissues during surgery may be responsible for the endometriosis implants sometimes seen in surgical scars (for example, episiotomy or Cesarean section scars). Transfer of endometrial cells via the bloodstream or lymphatic system is the most likely explanation for the rare cases of endometriosis that develop in the brain and other organs distant from the pelvis.
Finally, there is evidence that shows alternations in the immune response in women with endometriosis, which may affect the body's natural ability to recognize and destroy any misdirected growth of endometrial tissue.

Endometriosis Symptoms

What is endometriosis?

Endometriosis is the abnormal growth of cells (endometrial cells) similar to those that form the inside or lining the tissue of the uterus, but in a location outside of the uterus. Endometrial cells are cells that are shed each month during menstruation. The cells of endometriosis attach themselves to tissue outside the uterus and are called endometriosis implants. These implants are most commonly found on the ovaries, the Fallopian tubes, outer surfaces of the uterus or intestines, and on the surface lining of the pelvic cavity. They can also be found in the vagina, cervix, and bladder, although less commonly than other locations in the pelvis. Rarely, endometriosis implants can occur outside the pelvis, on the liver, in old surgery scars, and even in or around the lung or brain. Endometrial implants, while they can cause problems, are benign (not cancerous).
